American forces reportedly engaged twice as many Iranian missiles as the IDF

Israel conserved its air defense interceptors during the war on Iran, while the US expended significant portions of its own high-tech stockpiles, the Washington Post reported on Thursday, citing anonymous US officials.

American forces used more than 200 THAAD interceptors, around half of the total US stockpile, and over 100 SM-3 and SM-6 missiles, three officials told the outlet. Israel, by contrast, allegedly used only 100 Arrow interceptors and 90 David's Sling interceptors, some of them against less advanced missiles fired from Yemen and Lebanon.

"The United States absorbed most of the missile defense mission while Israel conserved its own magazines," the newspaper quoted Kelly Grieco, a senior fellow at the Stimson Center think tank, as saying. The figures suggest a "lopsided dynamic," WaPo wrote, although the Pentagon and the Israeli government both defended the balance of resources used.

The Pentagon has claimed less than $30 billion in direct spending, but skeptics say the cost of replacing spent munitions and lost assets, as well as the long-term impact on the American economy, could exceed $1 trillion.

While Washington's interceptor stockpiles have dwindled and new production cannot keep pace with demand, Tehran allegedly preserved much of its offensive capability. Iran has retained around 70% of its mobile launchers and missile stockpile, and regained access to 90% of underground military facilities damaged by US-Israeli bombings, according to earlier US media reports.

Despite President Donald Trump's repeated threats to resume attacks unless Tehran accepts his peace terms, many observers have suggested that repeated extensions of the fragile April ceasefire show he is seeking an off-ramp from the increasingly costly and unpopular conflict. Israel, meanwhile, is reportedly pushing Washington to finish the job while Tehran is weak.

Tehran has confirmed that it is reviewing Washington's updated proposals, but President Masoud Pezeshkian warned that "forcing Iran to surrender through coercion is nothing but an illusion." Foreign Ministry spokesman Esmaeil Baghaei said talks can succeed if the US ends its "piracy" against Iranian ships and agrees to release frozen funds, while Israel must end its war in Lebanon.
